The book Supporting Exports in Small and Medium-Sized Enterprises provides a significant insight into the internationalization of economic operations of small and medium-sized enterprises, focusing in particular on exports, which can benefit from support instruments and schemes co-financed with public resources. Considerations center around the role of the SMEs in the economy, their internationalization and economic premises of an export promoting policy. An attempt is made to assess the system of State aid in Poland in the light of the EU regulations. The final part provides an overview of institutions and instruments which, to a lesser or greater extent, contribute to the internationalization of small and medium-sized enterprises.
